Works citing a given DOI (best-effort)
Attempt to list works that cite a given DOI by querying the Crossref /works collection with filter=doi-from:<doi>. Limitation: Crossref does not publish inbound citations through the main REST surface; the authoritative inbound graph is served by Crossref Event Data (api.eventdata.crossref.org). Results here are best-effort and often empty. For total inbound-citation count, use the is_referenced_by_count field on /works/{doi}. Data licensed CC0 by Crossref.
